Adaptor Protein Receptor Tyrosine Kinase
Src like adaptor protein slap is an interaction partner of the e3 ubiquitin ligase cbl that can regulate receptor tyrosine kinases mediated signal transduction.
Adaptor protein receptor tyrosine kinase. G protein linked 2nd messengers. Receptor tyrosine kinases rtks are high affinity cell surface receptors that play a major role in the signaling pathways governing the fundamental cellular processes of proliferation differentiation metabolism survival and intercellular communications. Receptor tyrosine kinases rtks are the high affinity cell surface receptors for many polypeptide growth factors cytokines and hormones. When the receptor is activated the irs 1 scaffolding protein binds to it and brings with it binding sites to recruit a number of different signaling molecules such as grb2 sos ras to head down the mapk pathway but also pi3k which can lead to activation of pdk1 and protein kinase b important in regulation of glucose transport.
Receptor tyrosine kinases newer version heynowscience. Gain of function mutations of the receptor contribute to the transformation of acute myeloid leukemia aml. In this study we analyzed the role of slap in signal transduction downstream of the type iii receptor tyrosine kinase flt3. Proto oncogene c kit is the gene encoding the receptor tyrosine kinase protein known as tyrosine protein kinase kit cd117 cluster of differentiation 117 or mast stem cell growth factor receptor scfr.
Growth factor receptors with intrinsic kinase activity and those that signal through g proteins can promote tyrosine phosphorylation of the adaptor protein shc which link activated growth factor receptors to the ras signaling pathway and its subsequent association with the grb2 sos growth factor receptor binding protein 2 son of sevenless. Multiple transcript variants encoding different isoforms have been found for this gene. Progress in molecular biology and translational science. Kit was first described by the german biochemist axel ullrich in 1987 as the cellular homolog of the.
Of the 90 unique tyrosine kinase genes identified in the. Fms like tyrosine kinase 3 flt3 is an important growth factor receptor in hematopoiesis. The receptor tyrosine kinases rtks are the second major type of cell surface receptors that we discuss in detail in this chapter see figure 20 3d right. Hussain biology 97 427 views.
